Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION Vapour/air mixtures are explosive. Above 86°C explosive vapour/air mixtures may be formed. Above 86°C use a closed system, ventilation. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Cough. Headache. Laboured breathing. Nausea. Sore throat. Unconsciousness. Vomiting. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.  •SKIN MAY BE ABSORBED! Redness. Roughness. Skin burns. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Redness. Pain. Severe deep burns. Safety goggles, or face shield, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Burning sensation. Dizziness. Dullness. Headache. Shock or collapse. Unconsciousness. Do not eat, drink, or smoke during work. Rinse mouth. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: complete protective clothing including self-contained breathing apparatus). Separated from strong oxidants, food and feedstuffs. Well closed. Keep in a well-ventilated room. Do not transport with food and feedstuffs. Should be stored in iron or steel containers.

International Chemical Safety Cards m-CRESOL ICSC: 0646 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO YELLOW LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning producing toxic and irritating fumes. Reacts with strong oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: 5 ppm; 22 mg/m3 (skin) (ACGIH 1998). OSHA PEL: TWA 5 ppm (22 mg/m3) skin NIOSH REL: TWA 2.3 ppm (10 mg/m3) NIOSH IDLH: 250 ppm ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance severely irritates the eyes, the skin, the respiratory tract. Corrosive on ingestion. The substance may cause effects on the central nervous system. Exposure may result in unconsciousness. The effects may be delayed. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. Lungs may be affected by repeated or prolonged exposure to the vapour. The substance may have effects on the liver, kidneys and pancreas.
